Application filed August 15, 1914. Serial No. 856,889.

To aZZ whom it may concern Be it known that I, ROBERT A. LACKEY, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sash-Operating Mechanism, of which the following is a specification.

The modern method of hanging sash for factory purposes is to make the sash in sections which are bolted together and are hinged at the upper edge, so that when completed there will be a continuous sash, perhaps 150 feet in length, which opens and closes as a unit. Inasmuch as the sash is hinged at its upper edge, there is a constantly increasing load on the operating devices as the sash swings outwardly and upwardly in opening. Continuous sash is used both in monitor and saw-tooth roof construction, and while my invention may be applied to either, it is peculiarly adapted for use in saw-tooth roof construction wherein the movable sash normally lies at an angle to a vertical plane. There is thus an immediate and material load on the operating devices at the very start of the opening movement of the sash, and as above stated this load increases as the sash opens farther. I

It is the primary object of the present in vention to produce improved sash-operating mechanism so constructed'and arranged as to compensate for the increasing load of the sash, so that the sash may be operated by a substantially constant or uniform power in all positions of the sash. In carrying out this idea, I provide longitudinally movable operating means extending parallel to the sash, and a series of swinging devices spaced apart at suitable distances along the sash and connected thereto and to said operating means, each of said swinging devices comprising a plurality of members peculiarly mounted and pivoted together in such a manner as to afford an increasing leverage or thrust upon the sash in the progressive movements of the devices.

The invention also has reference to the specific construction and relation of the operating devices, and the manner of mounting the same upon the building framework.

In the accompanying drawings. Figure l is a plan view of a sash-operating device constructed in accordance with my-invention, the building framework and sash being shown in section. Fig. 2 is a view in front elevation of the operating-device and the sash. Fig. 3 is a plan view illustrating the means for mounting a pair of operating devices to swing in opposite directions. Fig.

.4 shows a device in side elevation, a portion of the building frame and sash appearing in vertical section. Fig. 5 is a view similar to Fig. 4 showing another one of the operating devices in side elevation, this device being inverted with respect to the one shown in Fig. at. Figs. 6 to 10 are plan views, more or less diagrammatic, showing one of the operating devices in progressively different positions from a point just off of the starting position to a point not quite to the extreme position.

I have shown in the drawings an exemplary form of'building framework which comprises upright an le bars A and crossing horizontal bars 13 suitably secured together. The sash C is hinged at'its upper edge at c in the framework, and in opening swings to the left, as viewed in Fig. 4.

The operating mechanism comprises a palr of longitudinally movable members 11 herein shown in the form of tension rods.

Suitable means is provided for moving these rods in opposite directions, but inasmuch connected with the sash at such intervals as required to maintain rigidity of the sash and prevent warping thereof. Some of these swinging devices are connected to the upper one of the tension rods ll and some to the lower rod, and inasmuch as these rods move in opposite directions the corresponding swinging devices will swing in opposite directions in moving the sash. The devices connected to the upper and lower tension rods 11 are inverted with respect to each other, but the construction of all may be identical and a description of one of the devices will suffice for all.

Referring to one of the devices which is connected to the upper tension rod, as shown in Figs. 1 to 4; An arm 12 which consists of upper and lower sections is pivoted atits rear end at 13 to the rear ends of a pair of plates 14 secured to the upper and lower arms, respectively, of a 'U-shaped bracket 15 which is suitably supported by means to be presently described. In efi'ect, the plates 14 constitute a part of the .bracket 15 but are made separate in the present instance for convenience in manufacture. Another arm 16 consisting of upper and lower sections is pivoted at its rear end at 17 to the forward ends of the plates 14. As shown in Fig. 1, the plates 14, and therefore the plane in :which pivot points 13 and 17 lie, extend obliquely with relation to the sash or to the arms ofthe bracket'15 which are perpendiculaa' to-the sash. A brace 18 consisting of upper and lower sections has its opposite'ends pivotedrespectively to the extreme free ends .ofthe arms 12 and 16. A sleeve 19 suitably fixed upon the operating rod 1'1 is pivoted on one of the parts of the swinging device, preferably the brace 18. A thrust link 20 has one end attached .to the joint between the arm 16 and the brace 18 by means of a suitable universal joint which preferably comprises a til-shaped clip 21, the sides of which overlap the ends of the sections of the arm 16 and brace '18, a bolt 22 pivotally securingthe said parts together, and a sleeve 2'3 fi-xed upon the thrust link 20 and pivoted to the base of the U-shaped .clip 21. The opposite end :of the thrust link 20 has a universal connection with the sash, which connection preferably .comprises an eye 24: :to which the thrust link is pivoted for verti- .cal movement, said eye being pivoted for horizontal movement upon the projecting web of a T-bar 25 which is attached to the sash and may extend horizontally the entire length of the same. The thrust links 20 of all of :the different operating devices may be attached to this T-ba-r'25.

.(Dne of the operating devices which is attached to .the lower oneof the tension rods 11;].- is shown at the right-hand side of Fig. '3 1and in Fig. 5, this operating device being inverted with respect to the others as before explained. The parts .of this device .are indicated by the same reference numerals arsed. for the device just described with the prime exponent added. In Fig. :3 the lefthand device is'opera-ted by the upper tension rod and swings toward the left, while the right-hand device is inverted and swings toward the right, being operated by the lower tension rod. The two devices may thus overlap each other without interfering. It will be understood that an approximately equal number of the upper and lower operating devices will be mounted along the sash, and inasmuch as said upper and lower devices swing in. opposite directions, any tendency new. and causing. -.the to warp,

skew, or bind by reason of an end thrustthereon, is neutralized by the oppositely moving operating devices.

The means herein shown for mounting the U-shaped supporting brackets 15'upon the framework of the building will now be described. The spacing of these supporting brackets, as hereinbefore suggested, is dictated by practical requirements in maintaining the sash in a straight line to move as a unit and in preventing warping of the sash. The upright angle bars A form a suitable support for attaching the brackets 15, but these angle bars are not always spaced apart the desired distances for mounting the brackets. Where one of the angle bars is properly situated, the construction illus .trated in Fig. 3 may be employed. This comprises a horizontal bar 26 tothe ends of which one or more of the 'U-shaped brackets 15 are secured, the bar being fixed to the upright angle bars A by means of a pair of angle pieces 27 and 28, clamped together and to the bars by means of bolts 29.

Where it is necessary to mount an operating device between two of the upright standards A, the construction illustrated in Figs. .1 and 2 may be employed. This comprises a horizontal rod 30 having its ends secured to two adjacent angle bars A by means of clips 31 and a vertical bar 32 having its upper end clamped upon the rod 30 and having its lower end bolted to a cross angle .bar B. One or more of the U-shaped supporting brackets 15 may be suitably fixed upon the mid-portion of the bar 32. In Figs. 1 and 2 a single upper operating device is shown as so mounted.

In Figs. 6 to 10, one of the upper operating devices is shown in progressively dif ferent positions. Fig. 6 shows the device just 011' starting position, Figs. 7 8 and 9 indicate the quarter, half, and three-quarters position, and Fig. 10 indicates the device just short of the extreme position, with the sash fully opened. Owing to the peculiar mounting and the pivotal relation of the parts of the device, a uniformpower applied to. the tension rods will develop a thrust of outwardly and upwardly the increasing load 2. Sashoperating mechanism comprising a device having two arms pivoted at their rear ends at spaced points lying in a plane oblique to the sash, and having a brace connecting the extreme free ends of the two arms, operating means connected to the device adjacent to one end of said brace, and means connected to the sash and to the device near the opposite end of said brace.

Sash-operating mechanism comprising a longitudinally-movable operating member, a plurality of swinging devices each comprising two arms pivoted at their rear ends on the building framework at spaced points lying in a plane oblique to the sash, and a brace connecting the free ends of said arms, the device being connected to said operating member adjacent to one end of said brace, and links each connected to the sash and to one of said devices near the opposite end of said brace.

4. In sash-operating mechanism, a U- shaped supporting bracket mounted on the building framework, a swinging device comprising two arms each composed of an upper and a lower section pivoted to the upper and lower ends of said U-shaped bracket, the pivot points of said arms being spaced apart and lying in a plane oblique to the plane of the sash, and a brace connecting the free ends of said arms, a longitudinally movable operating member connected to swing said device, and a thrust link arranged to transmit1 the swinging movement thereof to the sas 1.

The combination with a building framework and a sash hinged thereon at its upper edge, of longitudinally-movable operating means extending substantially parallel to the sash, swinging devices each comprising a pair of arms pivoted to the building framework and a brace connecting the free ends of said arms, the pivot points of said arms being spaced apart and lying in a plane oblique to the sash, said devices being connected to the operating means, and thrust links connecting the sash with said devices, the latter being arranged to provide an increasing leverage to compensate for the increasing load of the sash in opening.

In testimony whereof, I hereunto set my hand in the presence of two witnesses.
